Safeguarding NDA systems

Nondestructive assay measurements are more suscettible to error than is consistent with currently available instrument and physical security techniques. Measurement accuracy and control of sample geometry are being improved. However, little is being provided to protect equipment, measurement geometry, or data in these new systems. Four goals, if achieved, could increase overall performance and measurement confidence: automating measurements and equipment, monitoring of equipment performance, protecting equipment and data, and deploying equipment to assure that measurements and four nondestructive assay instruments are examined with respect to achieving these goals. 6 references, 7 figures
